6. To show how powerful he is, Mr. Avalos pushes on the wall with a force of 150 N for a whole minute!
The wall doesn't move. How much work did he do on the wall in this amount of time?

If the wall doesn't move, its mean that the work he did is 0 J.

Introduction

Hello my friend ! Here, I will help you. Alright, before it, I will to introduce to you about work (physics). In the world of physics, work is the amount of force exerted to cause an object to move a certain distance from its starting point. The amount of work will be proportional to the increase in force and increase in displacement. Amount of work can be calculated by this equation :

[tex] \boxed{\sf{\bold{W = F \times s}}} [/tex]

With the following condition :

  • W = work (J)
  • F = force (N)
  • s = shift or displacement (m)

Proof

How about a stationary object like a wall pushed by Mr. Avalos ? Yes it is 0 J. Let's prove it!

Give :

  • F = force of Mr. Avalos = 150 N
  • s = displacement of wall = 0 m
  • t = interval of the time = 60 s

Asked : W = work = ... J

Proven :

[tex] \sf{W = F \times s} [/tex]

[tex] \sf{W = 150 \times 0} [/tex]

[tex] \boxed{\sf{W = 0 \: J}} [/tex] (Q.E.D)
